Exploiting Cross-Lingual Representations For Natural Language Processing
… for most languages. In this thesis, I argue that cross-lingual representations are an effective means of extending NLP tools to languages beyond English without resorting to generous amounts of annotated data or expensive machine translation. These representations can be learned in an inexpensive …

Efficient and Composable Adaptation for Cross-Lingual Transfer
… to overfitting, lend them to applications in cross-lingual transfer, where data from "high-resource" source language(s) is employed to improve performance of NLP systems for (typically lower-resource) target languages. For instance, two independently trained PEFT modules, one for a specific …

Improving Parameter-Efficient Cross-Lingual Transfer for Low-Resource Languages
… data sources to achieve good performance across a range of resource scarcity. In this thesis, this question is addressed from two different perspectives in the context of modular and parameter-efficient approaches to cross-lingual transfer. Firstly, we propose different strategies for …

Cross-Lingual Word Sense Disambiguation for Low-Resource Hybrid Machine Translation
This thesis argues that cross-lingual word sense disambiguation (CL-WSD) can be used to improve lexical selection for machine translation when translating from a resource- rich language into an under-resourced one, especially when relatively little bitext is avail- able. In CL-WSD, we perform word …

Lost and Found in Translation: Cross-Lingual Question Answering with Result Translation
Using cross-lingual question answering (CLQA), users can find information in languages that they do not know. In this thesis, we consider the broader problem of CLQA with result translation, where answers retrieved by a CLQA system must be translated back to the user's language by a machine …

Systematic Comparison Of Cross-Lingual Projection Techniques For Low-Density Nlp Under Strict Resource Constraints
… researchers who must select an appropriate cross-lingual projection approach (and a high-density language from which to project) for a given low-density language. </p> <p>Finally, all the languages drawn from the Europarl corpus are actually HD, but for the sake of the evaluation testbed in …

Opinion Topic, Holder and Polarity in texts: exploration and automatic identification from cross-lingual data
… technology and the internet, more and more multilingual and multicultural information has become available on the web. The objective of the present dissertation is exploring and automatically extracting opinions from multilingual corpora. In pursuing this objective, a bilingual opinion-annotated …

Data-Efficient Bilingual Lexicon Induction with Pretrained Language Models
Bilingual dictionaries are essential language resources that play a crucial role in the development of modern multilingual and cross-lingual natural language processing (NLP) systems, particularly for resource-lean languages. Although there are 7,000+ languages spoken worldwide, existing bilingual …

Advancing Language Equity and Sample Efficiency in Task-Oriented Dialogue Systems
… majority and minority languages. Equitable multilingual TOD systems should not only be accessible (able to converse with the users in their language) but also useful (addressing specific needs of diverse linguistic communities). This thesis aims to promote language equity in dialogue systems …

Typology-aware neural dependency parsing : challenges and directions
… task of leveraging typology in the context of cross-lingual dependency parsing. While this linguistic information has shown great promise in pre-neural parsing, results for neural architectures have been mixed. The aim of the investigation put forth in this thesis is to better understand this …
